The CA3193A and CA3193 are ultra-stable, precision instrumentation, operational amplifiers that employ both PMOSandbipolar transistorsona singlemonolithic chip. TheCA3193AandCA3193amplifiersareinternallyphase compensated and provide a gain bandwidth product of 1.2MHz. They are pin compatible with the industry 741 seriesandmanyother ICopamps,andmaybeusedas replacementsfor741seriestypesinmostapplications. TheCA3193AandCA3193canalsobeusedasfunctional replacements for op amp types 725, 108A, OP-5, OP-7, LM11andLM714inmanyapplicationswherenullingisnot employed.Becauseoftheirlowoffsetvoltageandlowoffset voltage vs temperature coefficient the CA3193A and CA3193amplifiershaveawiderrangeofapplicationsthan most opamps and are particularlywell suited foruseas thermocouple amplifiers, high gain filters, buffer, strain gaugebridgeamplifiersandprecisionvoltagereferences.
